As many as one million individuals in the United States live with Parkinson's disease. While approximately four percent of people with Parkinson's are diagnosed before the age of 50, incidence increases with age. Parkinson's disease is a movement disorder with symptoms that continue and worsen over time. Symptoms include muscle rigidity, tremors, and changes in speech and gait. If you have been diagnosed with Parkinson’s disease, you may be eligible to participate in one of our research studies of an investigational medication for the treatment of Parkinson’s disease. Not currently enrolling. As a study volunteer, you may receive study-related exams and lab tests as well as study medication at no cost to you. Throughout the course of one of our studies, you will be carefully monitored by our experienced medical research staff. Financial compensation may also be provided for your time and travel. The studies may last up to 6 months with several scheduled visits at one of our clinic locations over that time, depending on the study.  If you are interested in participating in one of our Parkinson's disease studies, please call us for a no cost screening and evaluation or click here to complete our registration form and one of our friendly staff will contact you.
